Title: Air gap winding type rotary electric machine
Inventor: UCHIDA MITSUHIRO
IPC: H02K3/47
Filed: 1982-05-13
Abstract: PURPOSE:To rigidly hold a stator coil section in a circumferential direction by a method wherein a magnetic shield is provided at its inner peripheral part with a locking groove which has a groove width larger than the interval of adjacent stator coils and has an opening part half-opened, and an insulating support in the T form is fitted into the locking groove. CONSTITUTION:A magnetic shield 11 is provided at its inner peripheral part with a locking groove 11a which has a groove width larger than the interval of adjacent stator coils 4 and has an opening part half-closed due to projections 11b projected from both sides. Then, a longitudinal side part of an insulating support 13 in the T form is inserted between the adjacent stator coils 4, and a transverse side part thereof is fitted into the locking groove 11a. By so doing, since the insulating support is received in the locking groove with high strength, it becomes possible to rigidly hold the stator coil section in a circumferential direction.

Title: Method of interdigital type pattern exposure
Inventor: ISHIHARA SATOSHI
IPC: G03F1/00
Filed: 1978-07-07
Abstract: PURPOSE: To obtain an interdigital type pattern by using the interference fringes of two sets of coherent light and executing one simple mask displacement between them.  
     CONSTITUTION: A light sensitive material 4 is exposed to the interference fringes of coherent lights 1 and 2 through the opebing of a mask 3. Next, coherent lights 1' and 2' are projected to the light sensitive material 4 through the opening of a mask 3'. The interference fringes at this time are positioned in the intervals between the adjacent interference fringes of the previous step. To do so, the mask 3' must be moved parallel to the interference fringes of the previous step by a distance Δ. Carry out the second exposure in this state. The interference fringe patterns P 1  and P 2  thus obtained by the first and the second exposures become the interdigital type patterns of a constant pattern interval l respectively when the coherent lights are all plane waves, and the adjacent intervals of the interdigital type pattern vary as l 1 <l 2 <l 3  when the coherent light 1 or 1' is a plane wave one and the 2 or 2' is a cylindrical surface wave one.

Title: Rolling method for sheet material
Inventor: TAKEMURA KENJI
IPC: B21B1/22
Filed: 1980-06-19
Abstract: PURPOSE: To continuously roll an excellently shaped sheet material over a wide range of sheet breadth, by rolling a jointed part between two sheet materials while ajusting a contact position between the sheet material and a work roll and a roll bending force, in case of rolling sheet materials of different breadths.  
     CONSTITUTION: When a jointed part between two sheet materials is detected by an optical device, etc., at a proper position on the feed-in side of a rolling mill, an intermediate roll 12 is automatically shifted in the direction of roll axis so as to make the roll crown of a work roll 11 conform to a material to be rolled next, and besides, the roll bending force of a roll bender 14 is also adjusted. The position δ of the intermediate roll 12 (a distance between the side edge of rolled material and the side end of the intermediate roll 12), that is the distance of the side end of the intermediate roll 12 from the contact point between the work roll 11 and the material, is adjusted; hereby, the distribution of rolling pressure is changed, and the roll crown is also changed. Hereupon, the intermediate roll's position δ and the roll bending force are correlatively changed.

Title: Voltage measurement device
Inventor: TANIUCHI TETSUO
IPC: G01R15/24
Filed: 1981-05-28
Abstract: PURPOSE:To make it possible to completely eliminate irregular variation in optical output due to change in temperature by connecting conductive films provided on the Z faces of individual electro-optical crystals. CONSTITUTION:The Z face of a single crystal 1 of LiNbO3 is provided with transparent electrodes 7 and 7', and those transparent electrodes 7 and 7' are mutually connected electrically by a gold lead wire 8. On the other hand for the single crystal 1 that is cut in the direction perpendicular to the Z direction an electric field from electrodes 3 and 3' is applied in the direction of the X axis and when a laser light 2 is passed in the direction that is parallel to the Z axis through a deflector 4, the intensity of output of the laser light 2 that is output from the single crystal 1 through a 1/4 wave length plate 6 and a light detection element 5 varies in accordance with the applied voltage that is applied to the single crystal. Accordingly voltage is measured by this intensity of output. In this way in which the electrodes 7 and 7' are electrically connected, electric charges generated by change in temperature of the Z faces of a single crystal of LiNbO3 can be mutually nullified, and thereby generation of electric field that causes error in the measurement due to electric charge can be prevented.

Title: Exhaust gas purifier for engine attached to the outside of boat
Inventor: KAWASE SENJI
IPC: F01N13/02
Filed: 1978-07-06
Abstract: PURPOSE:To very surely purify exhaust gas in two stages, by providing two catalysts at a prescribed spacing in an exhaust gas passage and placing the first catalyst at a high-temperature part near a cylinder. CONSTITUTION:The exhaust gas is discharged from the cylinder 1b through an  exhaust port 1a so that the exhaust gas comes into contact with the first catalyst 9 for oxidation. The carbon monoxide and hydrocarbon in the exhaust gas are thus decreased. The exhaust gas is then passed through an exhaust cover 2 and holes 1c, 3a so that the gas comes into contact with the second catalyst 10 for oxidation of not yet oxidized carbon monoxide and hydrocarbon. The exhaust gas is then released through an exhaust pipe 4. Because the catalysts are provided in two stages, the exhaust gas is purified well. Since the first catalyst is located near the cylinder 1b, the oxidation is caused at the place where the temperature of the exhaust gas is still high. The efficiency of the purification is thus raised further.

IPC: F04D29/36
Filed: 1992-04-06
Abstract: PURPOSE:To prevent the lowering of sealing performance caused by the corrosion of an impeller vane and facilitate a countermeasure in the case of corrosion being developed by making the sealing direction of the impeller vane and packing the same as the axial direction of a vane. CONSTITUTION:The impeller vane 1 of a movable vane vertical shaft pump is fitted to an impeller hub 2, and the vane angle of the vane 1 is changed according to the operating state of the pump. An I-packing 3 is put between the sliding parts of the vane 1 and hub 2 so as to prevent the infiltration of seal water into the hub 2. Because of being expanded in the axial direction of the vane 1, the I-packing 3 is expanded even in the case of the sliding face of the vane 1 being corroded, so that sealing performance is not lowered. In the case of the corrosion of the impeller vane 1 being advanced, the corrosion part is removed by machining up to the position graduated previously on the vane 1, and the I-packing 3 is replaced with the one higher in height by one stage. The sealing performance can be thereby recovered to the same degree as the initial state.
